RemoteRAG: A Privacy-Preserving LLM Cloud RAG Service (2025.findings-acl)
Copied to clipboard
| Challenge: | Large language models (LLMs) have a tendency to generate factually incorrect or purely fictional responses, a phenomenon known as hallucination. |
| Approach: | They propose to use remote RAG to protect user query from privacy leakage . they introduce (n,)-DistanceDP to characterize privacy leakages of user query . |
| Outcome: | The proposed solution can resist embedding inversion attacks while achieving no loss in retrieval under various settings. |
LightMoE: Task-Aware Expert Availability Management for Memory-Efficient MoE-LLM Inference (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing solutions for balancing model accuracy with inference latency are limited due to memory constraints. |
| Approach: | They propose a framework for memory-efficient MoE inference that exploits the functional redundancy and temporal locality of expert activation. |
| Outcome: | The proposed framework improves accuracy-efficiency trade-off by 4.3% over pruned models and 2.4% over dynamic swapping methods while maintaining inference latency comparable to pruned model. |
